Urogenital myiasis caused by Lucilia sericata (Diptera: Calliphoridae) in a domestic rabbit in Italy.

The report describes a case of urogenital myiasis in a domestic rabbit Oryctolagus cuniculus L. (Lagomorpha: Leporidae) caused by Lucilia sericata (Meigen; Diptera: Calliphoridae) in region Emilia-Romagna (Northern Italy). The case, occurring in June 2018, is the first one involving L. sericata as an agent of myiasis in a domestic rabbit in Italy. Species identification was based on morphological investigations of males through identification keys. The rabbit developed the urogenital myiasis as a consequence of chronic enteritis causing an accumulation of faeces in the perianal and perineal region.

Identificación de larvas productoras de miasis obtenidas del cepario de la Universidad Colegio Mayor de Cundinamarca con importancia en salud pública / Identification of Myasis-producing Larvae from the Universidad Colegio Mayor de Cundinamarca

Resumen Las miasis son infestaciones parasitarias en humanos y animales causadas por estadios larvarios de moscas; son de distribución mundial y son una enfermedad frecuente en nuestro medio. En la literatura solo existen algunos casos reportados; por lo cual, su verdadera incidencia es difícil de establecer debido al sub-registro y ausencia de tipificación de larvas. Objetivo. Identificar, clasificar y caracterizar morfológicamente las larvas causantes de miasis como base para futuras aplicaciones e intervenciones en salud pública. Materiales y métodos. Se analizaron 262 larvas obtenidas del cepario de la Universidad Colegio Mayor de Cundinamarca que se encontraban almacenadas sin ningún tipo de identificación, organización e historia. Resultados. Se realizó la identificación con estereoscopio y claves dicotómicas de las familias Cuterebridae, Oestridae y Calliphoridae. Las especies encontradas son asociadas a diferentes tipos de miasis humana y animal, entre ellas; Dermatobia hominis, Dermatobia cyaniventris, Oestrus ovis, Cochliomyia hominivorax y Lucilia sp. Discusión. Las formas más comunes de este parasitismo son cavitarias y forunculares; causadas por Dermatobia hominis y Cochliomyia hominivorax, sin embargo, éstas no son de reporte obligatorio ante los servicios médicos humanos. Por lo tanto, es indispensable la información y capacitación de profesionales de la salud para la correcta conservación, identificación y reporte de las larvas extirpadas en pacientes con miasis, hasta el punto de ser considerada una práctica de rutina en el diagnóstico clínico.

Abstract Myiasis is the parasitic infestation of the body in humans and animals caused by larval stages of flies; such diseases are worldwide distributed and they are frequent in our environment. In the literature, there are only a few reports; therefore, its real incidence is difficult to be established due to sub-recorded cases and absence of larval typing. Objective. To identify, classify and morphologically characterize myasis-producing larvae of importance in public health. Material and methods. 262 larvae were analysed, obtained from the Universidad Colegio Mayor de Cundinamarca that were stored without any identification, organization and history. Results. Larvae were identified using a stereomicroscope and morphology was based on dichotomous keys of the Cuterebridae, Oestridae and Calliphoridae families. The species found are associated with different types of myiasis, including; Dermatobia hominis, D. cyaniventris, Oestrus ovis, Cochliomyia hominivorax, C. macellaria and Lucilia spp. Discussion. As a conclusion, we found that cavitary and foruncular were the most common forms of this parasitism in the collection from the Universidad Colegio Mayor de Cundinamarca. and that Dermatobia hominis and Cochliomyia hominivorax were the main involved species; however, these are not mandatory reporting species for medical services. Therefore, generating information about preservation, identification and recording of myasis-producing larvae, as well as training of professionals in public health might be considered as a routine practice for an accurate clinical diagnosis.

Repellent Action of Carapa guianensis and Caesalpinia ferrea for flies species of Calliphoridae family / Ação repelente de Carapa guianensis e Caesalpinia férrea paraespécies de mosacas da família Callip horidae

ABSTRACT: Myiases occur by the infestation of fly larvae in tissues of live vertebrate animals, resulting in economic loss. Phytotherapy is considered an important alternative in the control of insects, which may reduce the economic impacts. Carapa guianensis is a plant that has been studied as a repellent against mosquitoes and Caesalpinia ferrea is reported in tropical climates, and there are few studies about its repellent action. The present study was designed to evaluate the repellent action of s C. guianensis and C. ferrea plants on flies species of the Calliphoridae family. W.O.T. traps containing deteriorated bovine liver and herbs cream of at concentrations of 20 and 50% were used to catch the flies. It was reported that the creams containing C. ferrea at concentrations of 20 and 50% and C. guianensis at the concentration of 50% have repellent effect against species of Calliphoridae family.

RESUMO: Miíases ocorrem pela infestação de larvas de moscas em tecidos de animais vertebrados vivos, resultando em perdas econômicas. Fitoterapia é considerada uma alternativa importante no controle de insetos, o que pode reduzir os impactos econômicos. Carapa guianensis é uma planta que tem sido estudada como um repelente contra mosquitos e Caesalpinia ferrea Mart. é encontrada em climas tropicais, e há poucos estudos sobre sua ação repelente. O presente estudo foi desenhado para avaliar a ação repelente das plantas C. guianensis e C. ferrea Mart. em espécies de moscas da família Calliphoridae. Armadilhas WOT contendo fígado bovino deteriorado e creme de ervas em concentrações de 20 e 50% foram usadas para capturar as moscas. Verificou-se que os cremes contendo C. ferrea Mart. em concentrações de 20 e 50%, e C. guianensis, na concentração de 50%, têm efeito repelente contra as espécies da família Calliphoridae.

Forensic entomology and the estimation of the minimum time since death in indoor cases.

Eight cases that occurred indoors in which the insects played an important role in the mPMI estimation are presented. The bodies of socially isolated people and old people living alone were discovered in central Italy between June and November. mPMI ranged from a few days to several weeks. Insects were collected during the body recovery and the postmortem. Climatic data were obtained from the closest meteorological stations and from measurements performed on the site. Sarcophagidae and Calliphoridae species were present in 75% of the cases with Lucilia sericata and Chrysomya albiceps collected in 50% of the cases. Chrysomya albiceps was always found in association with Lucilia species. Scuttle flies (Phoridae) were found in 37.5% of the cases, confirming the ability of these species in indoor body colonization. We show that if sealed environment may delay, the insect arrival dirty houses may create the environment where sarcosaprophagous insects are already present.

Myasis occuring in a neonate.

Myasis is the infestation of skin by larvae or maggots of a variety of flies. It is a condition that occurs more commonly in adults who are living and/or have visited tropical countries. It rarely occurs in neonates, and even when seen, only few larvae are extracted. This case report describes myasis occurring in an 11-day-old female who had 47 larvae in her skin.

Ocular myasis and associated mucopurulent conjuctivitis acquired occupationally: A case study.

Ocular myasis and associated mucopurulent conjunctivitis in human eyes is a rare phenomenon. However, if the sheep bot fly abounds and poor hygienic environment prevails, the Oestrous ovis deposits its larvae in the conjunctival eye sac of human. The present paper reports a case study of ocular myasis among sheep farm workers caused by Oestrous ovis. The ocular myasis and the associated mucopurulent conjunctivitis are occupationally acquired in these cases. This study also suggests the treatment of patients and the recovery of the larvae.

Miasis de nasofaringe, completando ciclo biológico in vitro / Myasis of nasopharynx, biologic cycle completed in vitro

Introducción. Miasis es la destrucción de tejidos de animales, incluido el hombre, por larvas de moscas. Caso clínico. Paciente femenino de 13 años de edad con antecedente de convivencia con aves de corral, que presentó, 5 días previos a su ingreso, temperatura de 38° C, dolor y prurito nasofaríngeo. En el servicio de urgencias se diagnosticó como rinofaringitis bacteriana, prescribiéndole penicilina procaínica y clorfeniramina. A los 3 días refirió salida de gusanos por boca y nariz en número de 10. A la exploración física se apreció faringe con hiperemia, saliendo por nariz y boca gusanos activamente móviles de color blancoamarillento, de 10 mm de longitud y 3 mm de ancho, en número de 20. Enviados a la Facultad de Medicina de Puebla, donde completaron ciclo biológico. La mosca obtenida fue Dermatobia hominis, familia Enterebridae. En el hospital se le practicó extracción de 85 larvas utilizando anestesia general e irrigación continua. Fue dada de alta 10 días después, asintomática. Conclusiones. La miasis es poco frecuente y puede ocasionar grandes destrucciones de tejido.

Introduction. Myasis is the parasitism of organs and tissues of warm-blooded vertebrates by the larvae of flies of different species. Case report. Thirteen year old female. Her house is provided with running water and sewer she had contact with farm house poultry. She began presenting symptoms 5 days prior to admission she presented with nasal discharge and pharyngitis. Her temperature was 38° C. At emergency services the patient was diagnosed with bacterial pharyngytis. Penicillin and clorfeniramine were administered. Three days later, larvae started coming out of her nose and mouth. In total 10 larvae were documented. In emergency services at a hospital, physical examination revealed pharyngeal erythema and rinorrhea. The larvae were described as yellowish, 10 mm long and 3 mm wide. The worms were sent to the Department of Parasitology of the School of Medicine of Puebla, Mexico, where they completed the in vitro cycle and were identified as Dermatobia hominis (fly), belonging to the Enterebridae family. In the hospital, 85 larvae were extracted from the patient. She discharged after 10 days of asymptomatic hospitalization. Conclusion. Myasis is not frequent and it can cause great tissue destruction. Antibiotic administration is generally not warranted unless there is evidence of concomitant superinfection.
